How does a big casino affect rental properties?

Just like how the casino will let you bet 10,000 on a spin of the roulette wheel - they know they will win over time. 

In addition, a brand new casino is being built nearby, as well as new townhouse developments.

A brokerage who deals in SDRPs invested in real property rather than in "markers" in The Wall Street Casino!

Go to a casino and see if you can do it in one night.

(Think art show, craft shows, home shows.) some soldiered on but many can’t afford casino or convention center prices.

I could be wrong though, I can see rapid steelers fans doing a lot of bookings.There is a developing area within walking distance of stadiums, casino and major hospital and museums, but half are rehabbed and half are rough.any insight would be helpful!  

It is home to two casinos, Electric Boat, a Navy Sub Base, and a National Guard Base, so the potential for future renters is promising. 

I've only had one tenant out of 9 that I manage in the area that had to make a partial payment only because she and her husband both work at a casino which is closed.
